Struct PartitionContext 

pub struct PartitionContext {
    pub x: usize,
    pub y: usize,
    pub frame_width: usize,
    pub frame_height: usize,
    pub max_block_size: BlockSize,
    pub min_block_size: BlockSize,
    pub lambda: f32,
}

Partition context for decision making.

Fields

x: usize

Block position (x in pixels).

y: usize

Block position (y in pixels).

frame_width: usize

Frame width.

frame_height: usize

Frame height.

max_block_size: BlockSize

Maximum block size allowed.

min_block_size: BlockSize

Minimum block size allowed.

lambda: f32

Lambda for RD.

Implementations

impl PartitionContext

pub const fn new(frame_width: usize, frame_height: usize) -> Self

Creates a new partition context.

pub const fn at(self, x: usize, y: usize) -> Self

Sets the block position.

pub const fn with_size_range(self, min: BlockSize, max: BlockSize) -> Self

Sets the block size limits.

pub fn can_use_size(&self, size: BlockSize) -> bool

Checks if a block size fits within frame bounds.

pub const fn child_size(size: BlockSize) -> Option<BlockSize>

Returns the child block size for quad split.
